Hi Ankan,

Starting from MATLAB R2019b, the “sheart2” function can be used to return the Shearlet transform of a real-valued 2D image. The Shearlet transform can be specified by creating an “shearletSystem” object and adjusting the properties. You can refer to the documentation of the function for more details:

You can also check out ShearLab, a library developed specifically for processing images with shearlets at the following link:

Hope this helps!
